The inside of the filter box 1 is divided into a filter chamber and a water storage chamber by the filter cartridge 5. The brush roller 6 and the screw conveying rod 7 are both located in the filter chamber. The connecting pipe 2 is connected with the filter chamber, the water outlet pipe 3 is connected with the water storage chamber, the brush roller 6 rolls and overlaps with the inner wall of the filter cartridge 5, a driving member is provided in the filter box 1 for acting on the filter cartridge 5 and driving it to rotate, a collecting cylinder 8 corresponding to the brush roller 6 is provided in the filter box 1, the collecting cylinder 8 is in a horizontal direction and is located below the brush roller 6, the collecting cylinder 8 is fixed in the filter chamber, a discharge port 9 corresponding to the collecting cylinder 8 is provided on the filter box 1, the discharge port 9 is connected with the collecting cylinder 8, and the screw conveying rod 7 is located in the collecting cylinder 8;

[0026] When in use, chemicals are put into industrial wastewater to stir the industrial wastewater. The chemicals react with harmful substances in the industrial wastewater to form solid substances. The valve 4 is opened to guide the industrial wastewater into the filter cavity through the connecting pipe 2. The filter cartridge 5 is driven to rotate by the driving member. The industrial wastewater passes through the filter cartridge 5 and flows into the water storage cavity, and then is discharged through the outlet pipe 3. The solid substances remain on the inner wall of the filter cartridge 5 and rotate with the filter cartridge 5, driving the brush roller 6 and the spiral conveying rod 7 to rotate. The brush roller 6 rotates in the opposite direction to the filter cartridge 5. The solid substances remaining on the inner wall of the filter cartridge 5 are cleaned by the brush roller 6. The cleaned solid substances fall into the collecting cylinder 8. The solid substances are conveyed by the spiral conveying rod 7 so that the solid substances are discharged from the discharge port 9, so as to realize self-cleaning of the filter cartridge 5 and avoid clogging of the filter cartridge 5.

[0027] To summarize, when the present application is in use, the separation of industrial wastewater and solid matter is achieved through the rotating filter cartridge 5, and the solid matter remaining on the inner wall of the filter cartridge 5 is cleaned by the rotating brush roller 6. The cleaned solid matter falls into the collecting cylinder 8, and the solid matter is transported by the rotating spiral conveying rod 7 so that the solid matter is discharged from the discharge port 9 to achieve self-cleaning of the filter cartridge 5 and avoid clogging of the filter cartridge 5. This facilitates operation and improves work efficiency, and is therefore more practical.

[0028] like Figure 4 As shown, in some embodiments, the driving member includes a driving rod 10 rotatably disposed in the filter box 1, the driving rod 10 is in a horizontal direction, a motor whose output shaft is connected to the driving rod 10 is fixed on the filter box 1, a driving gear 11 is provided on the driving rod 10, the driving gear 11 is in a vertical direction and fixed on the driving rod 10, and an outer gear ring 12 meshing with the driving gear 11 is provided on the filter cartridge 5, the outer gear ring 12 is in a vertical direction and fixed on the filter cartridge 5;

[0029] Referring to the above, when in use, the motor works to rotate the driving rod 10 and drive the driving gear 11 to rotate together, and the outer gear ring 12 will rotate due to the meshing action and drive the filter cartridge 5 to rotate together, so as to drive the filter cartridge 5 to rotate.

[0030] like Figure 6 As shown, in some embodiments, two baffles 13 are symmetrically arranged on the collecting cylinder 8, both of which are inclined. The two baffles 13 are fixed on the collecting cylinder 8 and are symmetrically distributed with the brush roller 6 as the center;

[0031] Referring to the above, when the brush roller 6 cleans the solid matter remaining on the inner wall of the filter cylinder 5, the two baffles 13 can prevent the solid matter from splashing randomly due to the rotation of the brush roller 6, so that the solid matter falls smoothly into the collection cylinder 8.

[0032] like Figure 4 As shown, in some embodiments, an adjustment plate 14 is slidably provided on the filter box 1 and a return spring 15 is provided between the two.

[0033] Referring to the above, in actual use, as time goes by, the brush roller 6 will gradually wear away from the inner wall of the filter cartridge 5, thereby affecting the cleaning effect. In the present embodiment, the reset spring 15 always maintains an extruded state. When the brush roller 6 is worn, the elastic potential energy of the reset spring 15 causes the adjustment plate 14 to slide, thereby keeping the brush roller 6 always in rolling overlap with the inner wall of the filter cartridge 5 to ensure the cleaning effect.

[0034] like Figure 4 As shown, in some embodiments, the driving rod 10 and the brush roller 6 are connected by a transmission assembly to achieve the two rotating together. The driving rod 10 and the brush roller 6 rotate in the same direction, so the brush roller 6 and the filter cartridge 5 rotate in opposite directions.

[0035] With reference to the above, when the driving rod 10 rotates, the brush roller 6 is driven to rotate together through the transmission assembly, and is not affected by the position change of the brush roller 6, thereby improving the synchronization of use and making it more convenient to use.

[0036] like Figure 4 As shown, in some embodiments, the transmission assembly includes an outer rod 16 rotatably arranged on the filter box 1, the outer rod 16 is in a vertical direction, the outer rod 16 and the driving rod 10 are connected to each other through a first bevel gear assembly 17, the first bevel gear assembly 17 includes two meshing bevel gears, the two bevel gears are respectively fixed on the outer rod 16 and the driving rod 10, an inner rod 18 slidably matched with the outer rod 16 is rotatably arranged on the adjustment plate 14, the inner rod 18 is in a vertical direction and is slidably matched with the outer rod 16 in the vertical direction, the inner rod 18 and the brush roller 6 are connected to each other through a second bevel gear assembly 19, the second bevel gear assembly 19 includes two meshing bevel gears, the two bevel gears are respectively fixed on the inner rod 18 and the brush roller 6;

When the position of the brush roller 6 changes, the sliding cooperation between the inner rod 18 and the outer rod 16 makes the driving rod 10 and the brush roller 6 rotate together without being affected by the position change of the brush roller 6.

[0038] like Figure 1-Figure 2 As shown, the present application also proposes a purification device, including the above-mentioned filtering mechanism, and also including a stirring box 20, the stirring box 20 is connected with a water inlet pipe and an addition pipe, the water inlet pipe is used to supply industrial wastewater into the stirring box 20, and the addition pipe is used to add chemicals into the industrial wastewater, the free end of the connecting pipe 2 is connected with the stirring box 20, a stirring rod 21 is rotatably arranged in the stirring box 20, the stirring rod 21 is in a vertical direction, and a motor with an output shaft connected to the stirring rod 21 is fixed on the stirring box 20;

[0039] Referring to the above, when in use, industrial wastewater is supplied to the mixing box 20 through the water inlet pipe, and chemicals are added into the industrial wastewater through the addition pipe.
